19.1.2.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 24.334, clauses 5.1.1, 5.1.2, 10.2.1, 10.2.2, TS 36.331, clauses 5.2.2.4, 5.2.2.25, 5.10.1a, 5.10.3. Unless otherwise stated these are Rel-12 requirements.

[TS 24.334, clause 5.1.1]

The service authorisation for ProSe direct discovery and ProSe direct communication determines whether the UE is authorised to use ProSe direct discovery announcing or ProSe direct discovery monitoring or both, and to use ProSe direct communication, in a particular PLMN or when not served by E-UTRAN. In this release of the specification, ProSe direct communication is supported only for Public Safety ProSe-enabled UE. The service authorisation is either:

1) pre-configured in the UE. The pre-configured service authorisation may be stored in the ME, or in the USIM as specified in 3GPP TS 31.102 [17], or in both the ME and the USIM. If both the ME and the USIM contain the same parameters, the values stored in the USIM shall take precedence. The UE shall not use the pre-configured service authorisation if the contents of the USIM indicate that the UE is not authorised to use them (see 3GPP TS 31.102 [17]); or

[TS 24.334, clause 5.1.2]

The IP address of the ProSe function in the HPLMN may be pre-configured in the UE and in this case, the UE may use the pre-configured IP address. Alternatively, the FQDN of the ProSe Function in the HPLMN may be self-constructed by the UE, i.e. derived from the PLMN ID of the HPLMN. The UE may perform DNS lookup as specified in IETF RFC 1035 [10].

[TS 24.334, clause 10.2.1]

One-to-many ProSe direct communication is applicable only to ProSe-enabled Public Safety UEs. One-to-many ProSe direct communication can only apply when the UE is:

a) served by E-UTRAN and authorised for ProSe direct communication in the registered PLMN;

Upon receiving a request from upper layers to send or receive data for ProSe direct communication in a given group, the UE shall initiate the procedure for ProSe direct communication. For case a, the UE shall perform ProSe direct communication procedures specified in subclause 10.2.2. For case b and c, the UE shall perform ProSe direct communication procedures specified in subclause 10.2.3.

The UE shall obtain the ProSe direct communication policy parameters for that group as specified in subclause 5.

If the ProSe direct communication policy parameters indicate that the UE is configured to use IPv6 for that group, the UE shall auto-configures a link local IPv6 Address following procedures defined in RFC 4862 [15]. This address can only be used as the source IP address for one-to-many ProSe direct communication.

If the ProSe Direct communication policy parameters group indicate that the UE is configured to use IPv4 for that group, then the UE shall:

– use the configured IPv4 address for that group as source address; or

– if there is no configured IPv4 address for that group, use Dynamic Configuration of IPv4 Link-Local Addresses as specified in IETF RFC 3927 [16].

[TS 24.334, clause 10.2.2]

When the UE is served by E-UTRAN and intends to use the ProSe radio resources (i.e. carrier frequency) provided by an E-UTRAN cell, the UE requests the parameters from the lower layers for transmitting or receiving ProSe direct communication (see 3GPP TS 36.331 [12]). The UE shall perform direct communication only if the lower layers indicate that ProSe direct communication is supported by the network. If the UE in EMM-IDLE mode has to request resources for ProSe direct communication as specified in 3GPP TS 36.331 [12], the UE shall perform a service request procedure or tracking area update procedure as specified in 3GPP TS 24.301 [11]. Once the radio resources for transmitting or receiving ProSe direct communication are provided by eNodeB as specified in 3GPP TS 36.331 [12], the UE shall start ProSe direct communication.

[TS 36.331, clause 5.2.2.4]

1> if the UE is capable of sidelink communication and is configured by upper layers to receive or transmit sidelink communication:

2> if the cell used for sidelink communication meets the S-criteria as defined in TS 36.304 [4]; and

2> if schedulingInfoList indicates that SystemInformationBlockType18 is present and the UE does not have stored a valid version of this system information block:

3> acquire SystemInformationBlockType18;

[TS 36.331, clause 5.2.2.25]

Upon receiving SystemInformationBlockType18, the UE shall:

1> if SystemInformationBlockType18 message includes the commConfig:

2> if configured to receive sidelink communication:

3> from the next SC period, as defined by sc-Period, use the resource pool indicated by commRxPool for sidelink communication monitoring, as specified in 5.10.3;

[TS 36.331, clause 5.10.1a]

When it is specified that the UE shall perform a particular sidelink operation only if the conditions defined in this section are met, the UE shall perform the concerned sidelink operation only if:

1> if the UE’s serving cell is suitable (RRC_IDLE or RRC_CONNECTED); and if either the selected cell on the frequency used for sidelink operation belongs to the registered or equivalent PLMN as specified in TS 24.334 [69] or the UE is out of coverage on the frequency used for sidelink operation as defined in TS 36.304 [4, 11.4]; or

[TS 36.331, clause 5.10.3]

A UE capable of sidelink communication that is configured by upper layers to receive sidelink communication shall:

1> if the conditions for sidelink operation as defined in 5.10.1a are met:

2> if in coverage on the frequency used for sidelink communication, as defined in TS 36.304 [4, 11.4]:

3> if the cell chosen for sidelink communication reception broadcasts SystemInformationBlockType18 including commRxPool:

4> configure lower layers to monitor sidelink control information and the corresponding data using the pool of resources indicated by commRxPool;

NOTE 1: If commRxPool includes one or more entries including rxParametersNCell, the UE may only monitor such entries if the associated PSS/SSS or SLSSIDs is detected. When monitoring such pool(s), the UE applies the timing of the concerned PSS/SSS or SLSS.

SS-UE

– As defined in TS 36.508 [18], configured for and operating as ProSe Direct Communication transmitting device on the resources provided by different cells (as specified in the relevant procedure steps in Table 19.1.2.3.2-1).

– SS-UE2

– As defined in TS 36.508 [18], configured for and operating as ProSe Direct Communication transmitting device transmitting as well Synchronisation information on the resources provided by different cells (as specified in the relevant procedure steps in Table 19.1.2.3.2-1).

– When SS-UE2 is simulated, SS-UE2 and SS-UE1 transmit simultaneously.

UE:
